I'm running Dropbox (paid personal account) on Windows 10 (version 10.0.19045.7291) and the right-click context menu has completely disappeared from Windows Explorer. The sync overlay icons (green checkmarks etc.) are still showing correctly, but no Dropbox options appear when right-clicking files or folders.
Here's everything I've tried:
1. Restarted Dropbox
Quit via system tray icon and relaunched. No change.
2. Re-registered the DLL
Found the DLL at C:\Program Files (x86)\Dropbox\Client\DropboxExt64.93.0.dll and ran:
regsvr32 "C:\Program Files (x86)\Dropbox\Client\DropboxExt64.93.0.dll"
This succeeded without errors. Restarted Explorer and rebooted. No change.
3. Verified registry entries
The context menu GUID {ECD97DE5-3C8F-4ACB-AEEE-CCAB78F7711C} is present under HKEY_CLASSES_ROOT*\shellex\ContextMenuHandlers\DropboxExt and the InprocServer32 key correctly points to the DLL.
4. Checked Shell Extensions\Blocked
The Blocked key does not exist under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions. Nothing is blocking Dropbox.
5. Checked Shell Extensions\Approved
The 10 overlay icon GUIDs (FB314ED9 through FB314EE2) are all present and approved. However, the context menu GUID {ECD97DE5-3C8F-4ACB-AEEE-CCAB78F7711C} was missing from the Approved list.
6. Manually added context menu GUID to Approved
Ran the following as administrator:
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions\Approved" /v "{ECD97DE5-3C8F-4ACB-AEEE-CCAB78F7711C}" /t REG_SZ /d "DropboxExt" /f
Restarted Explorer and rebooted. No change.
Current state
- Overlay icons work correctly
- DLL exists and is registered
- Registry entries look correct
- Context menu GUID is now in the Approved list
- Still no Dropbox options in the right-click menu
Any ideas what else could be causing this? I'd like to avoid a full reinstall if possible.
